What's New in Watt Charging Speed

1.1.2

July 20, 2026

Improved timing of the rating prompt — it now only appears after a completed measurement or benchmark, never during one.

User reviews

Deceptive Description

This app doesn’t actually give you “real time” wattage as it claims. It attempts to calculate based on battery level changes but this often yields absurd results which are not technically possible.

Response from developer

You're right on both counts, and this review pushed us to fix it properly. Thank you. The absurd readings came from how we calculated wattage: iOS only reports battery level in coarse 5% steps, often with a delay, and our old approach measured over a short time window — so a delayed level jump could produce spikes that were physically impossible. Update 1.1.1 replaces this: wattage is now measured between observed level changes, so both endpoints sit exactly on a step boundary, and readings that would be distorted by delayed reporting after unlocking are discarded. The impossible spikes are gone. You're also right that "real-time wattage" oversold it. iOS doesn't give apps access to a hardware power meter — every reading is an estimate derived from battery level changes and your device's battery capacity. We've rewritten the App Store description to say exactly that, and the app now needs a few minutes before showing its first (reliable) number instead of showing a fast wrong one. If you give 1.1.1 a try and still catch an implausible reading, we'd genuinely like to hear about it.

측정하기 너무 힘듬..

화면이 꺼지면 측정이 안된다고 안내하면서, 화면은 자꾸 꺼지도록 되어있음. 계속 화면을 쳐다보면서 안꺼지게 터치해야함. isIdleTimerDisabled = true 가 필요함.

Response from developer

정확한 진단 감사합니다 — 말씀하신 그대로였습니다. 사실 앱에는 isIdleTimerDisabled 처리가 있었지만, 충전 상태가 "변경될 때"만 동작하도록 되어 있었습니다. 그래서 충전기를 먼저 연결한 뒤 앱을 여는 경우(대부분의 사용자가 이렇게 사용하시죠) 상태 변화가 감지되지 않아 화면이 계속 꺼졌던 것입니다. 1.1.1 업데이트에서 수정했습니다: 이제 앱을 열 때 이미 충전 중이어도 화면이 꺼지지 않으며, 앱이 다시 활성화될 때마다 설정을 재적용합니다. 더불어 측정이 중단되었더라도 세션 전체의 평균 전력을 표시하도록 개선했고, 벤치마크 테스트가 멈추는 문제도 함께 수정했습니다. 덕분에 가장 중요한 버그를 잡을 수 있었습니다. 업데이트 후에도 문제가 있다면 꼭 알려주세요!

A fuir

attention cet appli ne fait que calculer le temps entre un changement de % de batterie et estime une puissance de charge, ne vous faites pas avoir comme moi !

Response from developer

Vous avez raison sur la méthode — et c'est justement le problème : notre description ne le disait pas assez clairement. Merci de nous l'avoir signalé, nous l'avons corrigée. Pour être totalement transparent : iOS ne donne à aucune app l'accès à un wattmètre matériel. Estimer la puissance à partir de la vitesse de montée du niveau de batterie, combinée à la capacité exacte de la batterie de votre appareil, est la seule méthode possible — c'est ce que font toutes les apps de ce type. La nôtre aurait simplement dû l'assumer dès la première ligne. Depuis, deux choses ont changé : la description sur l'App Store explique désormais honnêtement comment l'estimation fonctionne et ses limites, et la mise à jour 1.1.1 rend cette estimation nettement plus fiable (mesure entre les changements de niveau observés, plus de pics impossibles, moyenne de session après interruption). Si vous lui redonnez une chance, nous serions heureux d'avoir votre avis — et si l'app ne vous convient toujours pas, votre critique nous aura au moins aidés à être plus honnêtes. Merci.
